Difference in removing all / single subscriber

[tbusser]

I was looking at the removeSubscriber method of the Channel object and I noticed something that I can't explain.

When removing a specific subscriber you set the channel property of the subscriber to null before removing it from the array of subscribers. When all the subscribers get cleared due to the id param being null the array is simply cleared and the channel property on all the subscribers don't get reset to null.

Is there a specific reason for this or is it an oversight?
